Bramalea Woods faces fewer hazards than 89% of Canadian towns
The national fire record shows next to nothing around Bramalea Woods, 0% of the land within 25 km since 1986 (0.000% a year). Earthquake risk in Bramalea Woods is ordinary: NRCan’s model puts building losses at $0.030 a year per $1,000 of value, close to the typical town’s $0.030. Radon is lower than usual: 0% of tested homes in the survey area topped the guideline, against 6.6% for the typical town. Bramalea Woods grades A for hazard risk; wildfire is low here, so it earns no credit.

Bramalea Woods grades A for hazard risk
Earthquake risk and radon make Bramalea Woods’ grade; wildfire can only lower it, never raise it, and flood studies are listed but not scored.
Its place: #105 of 866 in Ontario and #417 of 2,589 Canadian towns.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Wildfire is rare near Bramalea Woods: 0% of the land within 25 km burned since 1986, 0% within 5 km
Fires mapped since 1986 around where Bramalea Woods’ residents live, and the fuel next to their homes.
A burn rate of 0.000% a year keeps Bramalea Woods in the low band (the typical Canadian town: 0.000%).
Little near Bramalea Woods’ homes can carry a forest fire; only 0.1% of the land within 5 km is forest fuel, and 3.9% within 25 km.
Shares of land within 5 and 25 km of populated blocks: burned at least once in 1986–2025 (CWFIS burned-area composite), forest fuel and grass (fire behaviour fuel types, 2026, 250 m grid).

Get ready for what Bramalea Woods faces
Practical steps for Bramalea Woods’ hazards, most pressing first.
- Test for three months in winter.
- Over 200 Bq/m³: fix it.
- Kits are cheap; pros test too.
- Never drive through floodwater.
- Move papers and medicines upstairs.
- Ask whether your street is mapped.
- Clear needles and wood nearby.
- Keep a grab-and-go bag ready.
- In smoke, stay in; filter air.
- Has it had a radon test?
- Check the address on the flood map.
- Are flood and wildfire insured?
What this data can and can’t tell you
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Bramalea Woods’ census subdivision (a neighbourhood shows its city’s).
- Wildfire counts one way. For Bramalea Woods, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Bramalea Woods is its health region’s, the survey’s design unit.
- Flood studies aren’t flood zones. NRCan’s inventory says where flood mapping exists, not where water goes; the map’s owner is the authority for Bramalea Woods.
